4 Claims. 1

The present invention relates to hair preparations, and more particularly to a preparation having utility as a hair dressing.

The object of the present invention is to provide a new and improved hair preparation which is made from comparatively inexpensive and easily available materials; which has a viscosity high enough to maintain the hair straight, dressed and well-groomed; which imparts an attractive gloss to the hair; which has a color well suited for hair dressing; which has a nonobjectionable odor; which does not develop rancidity; which is non-drying and therefore maintains the hair soft; which forms a thin protective non-tacky adhesive film of non-greasy characteristics on the hair; and which can be readily washed off with soap and water.

In carrying out the features of the present invention, an aliphatic alcoholic ester of abietic acid such as methyl abietate or a hydrogenated alcoholic ester of abietic acid such as methyl abietate hydrogenated is employed as an ingredient of the hair preparation. A 30% hydrogenated methyl abietate has been found particularly suited for this purpose. This abietate, which is comparatively inexpensive and easily available, is soluble in alcohol, and forms there- With a clear solution which does not turn cloudy when cooled to C. Furthermore, this abietate has a very high viscosity which enables it to keep the hair in place, straight and well-groomed; it has a very pale yellow color which is suitable for commercial hair preparations; it has a slight non-objectionable odor and unlike vegetable oils does not develop rancidity on standing; it im-- parts an attractive luster to the hair; it is substantially non-drying so that the hair does not become stiff, but appears soft; it forms a thin protective adhesive non-tacky, non-greasy film which covers the hair and scalp and prevents loss of scalp oils and consequent dryness of the scalp; and it can be readily washed off the scalp with soap and Water.

As a specific example of a preparation which is found suitable in accordance with the present invention a 30% hydrogenated methyl abietate is dissolved in isopropyl, ethyl, butyl alcohol or other harmless, volatile solvents. This abietate may constitute 3 to 50% of the preparation. A

' specific composition may, for example, comprise about 10% of 30% hydrogenated methyl abietate and about 90% ethyl alcohol. This preparation may have perfume added to it.

2 Other alcoholic esters of abietic acid which may be used in accordance with the present invention are ethyl abietate, ethylene glycol ester of abietic acid. diethylene glycol ester of abietic 5 acid, triethylene glycol ester of abietlc acid and glycerol ester of abietic acid. These esters may be of hydrogenated or non-hydrogenated abietic acid, and when adjusted in solution with alcohol or other volatile solvents, produce an eifective hair dressing preparation.

We have described what We believe to :be the best embodiments of our lnventiom We do not wish, however, to be confined to the embodiments shown, but what we desire to cover by Letters Patent is set forth in the appended claims.

We claim:

1. A non-drying hair preparation free from dyes, and containing essentially an alcoholic solution of a hair fixative ingredient of the class consisting of the esters of abietic acid and the hydrogenated esters of abietic acid in proportions of 3 to 50% 2. A non-drying hair preparation free from dyes and comprising essentially an alcohol solution of hydrogenated methyl abietate in proportions of 3 to 50%.

3. A non-drying hair preparation free from dyes comprising essentially an alcohol solution of 3 to 50% of about 30% hydrogenated methyl 30 abietate.

4. A non-drying hair preparation free from dyes comprising essentially about of about hydrogenated methyl abietate in alcohol solution. ALLEN L. OMOHUNDRO.
